In a method for internal cleaning of an implanted infusion system, comprising an infusion pump connected on its outlet side to a catheter (12) via a nonreturn valve (14), a flushing port (2) also being provided downstream the nonreturn valve and upstream the catheter, a first flow (Q1) of cleaning fluid is passed through the infusion pump and the nonreturn valve. A second flow (Q2) of secondary fluid is supplied through the flushing port, and a third fluid flow (Q3) is discharged through the flushing port. A device for such a cleaning comprises pumping means connected to the flushing port for supplying the second flow of secondary fluid, intended for diluting or otherwise modifying the cleaning fluid passing through the infusion pump and the nonreturn check valve, and for discharging the third flow. <IMAGE>
